How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with a single integer field 'distance' representing the minimum number of single-character insertions, deletions, or substitutions required to transform string a into string b.
Example use cases
Fuzzy name matching for deduplication
“I have two customer names — 'Jonathan Smith' and 'Jonathon Smyth' — can you calculate their edit distance so I can decide if they're likely the same person?”
Spell-check candidate scoring
“I want to rank spell-check suggestions for the misspelled word 'recieve' — can you calculate the Levenshtein distance between 'recieve' and 'receive' so I can score how close they are?”
Password similarity validation
“Check the edit distance between the old password 'Hunter2024' and the new password 'Hunter2025' — I want to reject new passwords that are too close to the old one.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/text/levenshtein?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, fast, authoritative edit-distance integer for two short strings (up to 256 chars each) without building your own algorithm — ideal for fuzzy matching, deduplication, spell-check scoring, or input validation pipelines where a pay-per-call micro-cost is acceptable.
Side effects
- Input strings exceeding 256 characters will be rejected
- Missing 'a' or 'b' fields return a validation error
- Payment failure or insufficient USDC balance returns HTTP 402
- Server-side quota exhaustion may return rate-limit errors
